What about migrations and model changes when using non-relational / special databases?

Short answer: Migrations support may be limited or unavailable. May require manual scripts or provider-specific tooling. Consider NoSQL-specific approaches for schema changes.

Real-world example (ShopNest)

When ShopNest adds a DiscountCode column, you create a migration, review the SQL, then apply it on staging before production.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
